Installing over an older version and other notes

Note
Ubuntu commands installed as snap packages can’t create arbitrary files under /tmp. This is for example the case by default for pdftk which is used by Recoll to extract PDF attachments. For best results, set TMPDIR to a location which belongs to you (e.g. inside your home, with something like export TMPDIR=~/tmp in your shell startup script). Recoll could conceivably work around the problem all by itself, but I find it in bad taste to create temporary files in an arbitrary location inside your home.

1.20 to 1.39 indexes are fully backward compatible. No need to reindex when upgrading.

Always reset the index if you do not know by which version it was created (e.g.: you’re not sure it’s at least 1.18). The best method is to quit all Recoll programs and delete the index directory (rm -rf ~/.recoll/xapiandb), then start recoll or recollindex.

recollindex -z will do the same in most, but not all, cases. It’s better to use the rm method, which will also ensure that no debris from older releases remain (e.g.: old stemming files which are not used any more).

On Windows, the index is located by default in C:/Users/[yourlogin]/AppData/Local/Recoll/xapiandb

Case/diacritics sensitivity is off by default. It can be turned on only by editing recoll.conf ( see the manual). If you do so, you must then reset the index.

Changes in Recoll 1.39.0

  • Indexing: enable indexing non-alphanumeric characters as separate terms by listing them in the indexedpunctuation configuration variable. This is a very small change with almost no impact on the normal indexing when not used, but, when configured, it allows discriminating searches for, e.g., 1.50% and $1.50.

  • Fixed menus floating around under Gnome/Wayland (also in 1.38.2).

  • Fixed preview window mistakenly using a QTextBrowser instead of a proper HTML engine because of a build glitch (also in 1.38.2)

  • Fixed GUI not loading zh_CN messages.

  • Updated simplified Chinese translation.

Minor releases at a glance

  • 1.39.1

    • GUI: add possibility for switch light/dark mode according to the desktop setting. Needs qt 6.5+ and does not work on all desktops.
